Fig. 44 is a front view of parts seen in Figs. 42 and 43, and a portion of the means for moving laterally the carriage for the calculating I mechanism. Fig. 45 is a detail view of one of the keys, the stop therefor, and the contiguous part of the supplemental frame for supporting said key.

The illustrated exemplification of this invention comprises a frame, a key-board, an actuating member, means for automatically locking the actuating member after a predetermined number of operations thereof, recording and controlling members, and multiplying, calculating and printing mechanisms. It will be understood, however, that one or more of said devices may be dispensed with, if desired.

The frame 1 which is of any suitable form, size and construction, preferably comprises upright sides and a cross-bar 2, each upright side being provided with a plurality of lengthwise; slots 3, Figs. 1 and 20, arranged one in advance of the other in .horizontal alineme'nt, and the cross-bar 2 being disposed between the upright sides and having its ends contiguous to the slots 3, and beingl adjustable lengthwise of said slots and eld in position by screws 4, Fig. 25, passed through the slots 3 and into the ends of the cross-bar 2.

The key-board which is also of any desirable form, size and construction, usually consists of keys 5, 6, 7 and 8. Said keys 5 are arranged in series and are carried by supplemental frames 9 which extend side by side lengthwise of the front end of the frame 1, and each comprise top,-bottom and end bars 10, 11, 12 and 13. Each supplemental frame 9 serves to carry a series of the keys 5 and is detachably secured to the frame 1., having one end thereof provided 'with opposing shoulders 14, 15, Fig. 1, for

detachably engaging opposite surfaces of a cr0ss-bar 16 of the frame 1, and its other end provided with a shoulder 17 for engaging the upper surface of a frame-cross-bar 18 opposed to the cross-bar 16, the shoulder 17 being detachably secured to the cross-bar 18 by any desirable clamping means, as the screw 19. The cross-bar 16 is provided with separated shoulders 20 which engage outer faces of the shoulders 14 of the right-hand and left-hand supplemental frames 9, and thus prevent lateral movement of the front ends of the frames 9 relatively to the frame 1.

As best seen in Figs. 1 and 3, each of the keys 5 is provided with a cylindrical shank 21 movable endwise in bearings in the top and bottom bars 10, 11 of the corresponding supplemental frame 9 and formed at its lower end with a lengthwise threaded socket split longitudinally, said socket receiving a lengthwise part 22 having one end threaded and adjustable endwise in the socket and its other end provided with an engaging face. These parts 22 form means adjustable re1atively to the keys 5 for transmitting motion therefrom. Each cylindrical shank 21 is held in its elevated position by a spring 23, and is provided withmeans, as a sheet metal plate, det achably secured thereto and formed with a plurality of arms 24, 25, 26, 27, the arms 24. 25 extending parallel to the shank in opposite directions. The arms 24 coact with the top bars 10 of the supplemental frames 9 to limit the upward movement of the keys 5, and the lower ends of the arms 25 are separated from the shanks 21 and movable in guides 28 in the bottom bars 11 of said supplemental frames for preventing the rotation of the shanks 21. The arms 26, 27 project laterally from the shanks 21, are spaced a distance apart, and are moved successively into engagement with locking means carried by the supplemental frames 9. Each series of the keys 5, with the exception of the left-hand series, contains nine keys, each distinguished by one of the units 1 to 9, inclusive, said units being progressively arranged. The left-hand series contains eight ofthe keys 5, each being distinguished by suitable words, as notes, checks, drafts, etc.

The key 6, Fig. 45, is arranged in the lefthand series of the keys 5 in transverse alinement with the lowermost, or front, keys of the remaining series of the keys 5. Said key 6 is termed ditto key, is provided with a cylindrical shank having a plurality of substantially V-shaped notches, and is held in either its elevated or depressed posi- T to the line of movement of the key 6, and

having one end supported in a socket in the left-hand supplemental frame 9 and engaged by a spring 30, and its other end pointed and adapted to enter the sockets of the shank of the key 6, and to be automatically forced out of said sockets by the tapering Walls thereof as the key 6 is moved downwardl or upwardly.

In the ill ustrated construction of my invention, the locking means, Figs. 1 and 3, coacting with the arms 26, 27 of the keys 5, consists of a plurality of rock-shafts 31 journaled in the end bars 12, 13 of the sup plemental frames 9, and pivoted locking members 32, one for each key 5, fixed in series on the rock-shafts 31. Each locking member 32 is formed with shoulders 33, 34 spaced apart, and arranged above and below the axis of the shaft 31 provided therewith, the upper shoulder having a beveled engaging face The rock-shafts 31 are provided with arms 36, Fig. 34, fixed thereto and formed with cutouts 37 which receive shoulders 38 carried by the end walls 13 of the supplemental frames 9. Springs 39 are pivotally supported at corresponding ends on the supplemental frames 9, and are pivoted at their other ends to the free or upper ends of the arms 36, the pivots for uniting contiguous ends of the arms 36 and the springs 39 being held by said springs on opposite sides of lines, as 40, drawn through the axes of the rock-shafts 31 and the springs 39. The movement of the rock-shafts in one direction is limited by the engagement of the walls of the cutouts 37 with the shoulders 38, and in the opposite direction by the engagement of the shoulders 34 of the locking members 32 with the bottom bars 11 of the sup lemental frames 9.

If the operator depresses one of the keys 5 when the remaining keys of the series including said key are in their elevated position, the lower arm 27 on the key being depressed. will engage the shoulder 34 of the corresponding locking member 32 and force said member 32 into its operative position with its upper shoulder 33 engaged with the arm 26 of the depressed key for preventing the return movement thereof. When said locking member is forced into operative position, as described, it rocks the shaft 31 provided therewith, and thus simultaneously moves all of the other locking members 32 fixed to said roekshaft 31, so that the beveled engaging faces thereof will be in position to be engaged by the arms 26 of the remaining keys. Consequently, when one of the remaining keys is depressed, the arm 26 thereof will engage the beveled face 35 of the corresponding locking member 32 and reverselv move the rockshaft provided therewith and the remaining locking members thereon, and thus release the key first depressed. If the movement of the key last actuated is continued, the lower arm 27 thereof will engage the shoulder 34 of the corresponding locking-member and cause the same to assume its operative position and prevent the return of said key.

The locking members 32 are returned to their normal or inoperative position by any suitable means, here illustrated, Fig. 34, as comprising substantially parallel links 41, and longitudinally movable bars 42, 43, the links 41 having their upper ends pivoted at the sides of the machine, and the bar 42 being arranged crosswise of said machine and having its extremities pivotally supported on the lower ends of the links 41, and being provided with a series of upwardly extending shoulders 44 coiiperating, respectively, with laterally extending shoulders 45 on the arms 36 of the rock-shafts 31. The bar 43 extends lengthwis of the frame at the lefthand side of the front thereof and at an angle to the bar 42. As best shown in Fig. 36, the rear end of the bar 43 is pivoted to the front end of a link 46 having its other end pivoted to one arm of a bell-crank lever 47 supported by the frame, and having its other arm formed with a lengthwise slot which receives a depending shoulder 420, Figs. 34 and 36, provided on one end of the bar 42. The bar 43 is held in its normal position by a spring 48 and is moved rearwardly against the action of said spring by the vertically reciprocating key 7, Fig. 41, or by means, Fig. 33, provided on the actuating member. As the bar 43 is moved rearwardly, the link 46 and the bell-crank lever 47 move the bar 42 to the right and rock from their operative position any of the locking members 32 previously forced to said operative position by the depression of the keys 5. As best seen in Fig. 41. the key 7 is connected to one arm of a bell-crank lever 49 having its other arm formed with a lengthwise slot which receives a shoulder 430. Figs. 36 and 4], on the outer face of the bar 43. The depression of the key 7 thus actuates the lever 49 to move the bar 43 against the action of the spring 48 for causing the link 46 and the lever 47 to move the bar 42 to the right.

The means provided on the actuating member for operating the bar 43 consists of a tappet 50, Figs. 2 and 33. pivoted to the actuating member and having an engaging end or shoulder for courting with a shoulder 51, Fig. 41, fixed to the bar 43 and depending therefrom. and having additional engaging shoulders 52. Fig. 33, which coact with a stop 54 carried by the actuating member. A spring holds said tappet 50 in its normal position with the shoulder 52 in engagement with the stop 54. When the actuating member is rocked on its axis to force the engaging end of the tappet 50 forwardly, said end encounters the shoul-
